AfterQuery is hiring software engineers to author original coding tasks based on real codebases, used to evaluate and train advanced AI coding agents. You'll connect one of your own private codebases and turn a real engineering problem from it into a task: a clear, maintainer-style issue, a hidden test suite, and a reference solution. Every submission is validated automatically before it's approved, so the ideal candidate is someone who can write a problem a solid engineer would recognize as real work, and a test suite that verifies a solution the way a careful reviewer would.

Why Apply
Exceptional Pay: $150/hour, fully remote, on your own schedule
Real Engineering: Work from your own codebases on problems a solid engineer would recognize as real work
Startup Exposure: Contribute directly to frontier AI evaluation with a YC-backed research lab
